You need to change the jumper setting...to the appropriate mode...or Windows will never recognized the drive.
Who manufactures the drive...and what is the model number (not serial number) on it?
FWIW: When you say "initialize the drive", I don't think you mean that in the context that many will interpret it. Initialization when used re hard drives...implies that the hard drive needs to be formatted in order that Windows can see and use it.
Thank you for the response. The HD is Hitachi Deskstar HDS722540VLAT20. I checked Hitachi's site, but their models for Deskstar only go back to HDS728xxxx... I tried a number of jumper settings - I think I need a couple more of those tiny plastic bridges though, as some combinations require up to 4 at a time, I just don't know where to get them from.
And I said 'initialize' because that's what I thought Disk Manager calls it... so if that has to reformat the HD for Vista to see it, there's no way to save the data on it?
